Abstract: Disclosed are a stone-plastic floor and a method of preparing the same. The resin substrate of the stone-plastic floor of the present disclosure is prepared by using raw materials with specific components and amounts, without using any plasticizing agent, toughening agent and foaming agent and without environmental hidden dangers. The resulting stone-plastic floor has high strength, high hardness, excellent shrinkage performance and no environmental hidden dangers, and can tolerate direct sunshine, and has good stability and long service life for use safety. The method of preparing the stone-plastic floor of the present disclosure has simple processes, enabling online continuous production with high production efficiency.

Abstract: The invention relates to composite floorings, more particularly to a soundproof composite flooring of magnesium sulfate and solid wood. The soundproof composite flooring includes a paint layer, a solid wood layer, a magnesium sulfate substrate layer, and a soundproof layer which are sequentially arranged from top to bottom; the solid wood layer and the magnesium sulfate substrate layer are bonded via AB glue by cold pressing or via a hot-melt adhesive; a plurality of cylindrical holes are arranged along edges of an upper surface of the magnesium sulfate substrate layer, and a buffer structure is arranged in each of the cylindrical holes; the buffer structure includes a rubber base which fits a bottom of the cylindrical holes, and a support disk which is opposite to the solid wood layer. The rubber base and the support disk are connected by a rubber column.
